I bought a set of Hard Krome 2.75 big straights for my 04 Sabre. I have had one mechanic tell me that re jetting is NOT necessary, he is the ONLY one I have heard say this. HK reccommends jetting and every other mechanic I have talked to says it won't run right unless I rejet. Has anybody put a full exhaust on and Not jetted and if so, did the bike run smoothly? Is this one mechanic that told me I don't need to way off with his info? Thanks for any feedback.
